TJ2 Posted January 12 Share Posted January 12 pinellas county freshwater leaning to all being LESC (fresh water and heads not quite round enough for GRSC) i did pick up a greenish sheen on the male which made me question Quote Link to comment Share on other sites More sharing options...
Snake Fingers Posted January 12 Share Posted January 12 (edited) Greater. Note head shape and green sheen. Edited January 12 by Snake Fingers I could be wrong though. Quote Link to comment Share on other sites More sharing options...
Aidan B Posted January 12 Share Posted January 12 Mostly Lesser Scaups, the male is unidentifiable. Head sheen in scaup is notoriously unhelpful in IDing them, I've seen Lesser with a greenish sheen and Greater with a purplish sheen. 5 Quote Link to comment Share on other sites More sharing options...

This is very, very true. Way too many people(including me when I first started out), considered the color of the head sheen to be one of the biggest ID factors in Scaup…it’s actually not helpful at all unless you have both species side by side in the most ideal and same lighting conditions possible. 2 Quote Link to comment Share on other sites More sharing options...

I was lucky to be taught this before I IDd my first Scaup. 1 Quote Link to comment Share on other sites More sharing options...
Quiscalus quiscula Posted January 12 Share Posted January 12 Head sheen can be quite useful in scaup ID and should not be totally disregarded, although it should never be used as the sole factor in an identification. Percentage wise, it is still more likely than not that a scaup with purple head sheen is a Lesser, and with green sheen a Greater. 3 Quote Link to comment Share on other sites More sharing options...

It's one of those marks that can't be used to solely ID a bird, but is a fairly reliable indicator given the right conditions. On a sunny day, where all the birds are looking the same direction and are resting, it's fairly reliable. On a windy, overcast day where all the birds are diving? Pretty much useless. 2 Quote Link to comment Share on other sites More sharing options...
Avery Posted January 12 Share Posted January 12 All the birds are LESC except for the male with it's head tucked, which is a GRSC 2 Quote Link to comment Share on other sites More sharing options...

The head lacks a strong peak, instead being largely rounded and tallest above the eye. The eye is also farther up in the head than a LESC. 2 Quote Link to comment Share on other sites More sharing options...
